Question: A new type of band has been developed by a dental laboratory for children who have to
wear braces. The new bands are designed to be more comfortable, look better, and provide
more rapid progress in realigning teeth. An experiment was conducted to compare the mean
wearing time necessary to correct a specific type of misalignment between the old braces and
the new bands. One hundred children were randomly assigned, 50 to each group. A summary
of the data is shown in the table.
